NAME

       MPI_Lookup_name - Finds port associated with a service name

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Lookup_name(char *service_name, MPI_Info info,
	    char *port_name)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_LOOKUP_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR)
	    CHARACTER*(*)  SERVICE_NAME, PORT_NAME
	    INTEGER	   INFO, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Lookup_name(const char *service_name, const MPI::Info& info,
	    char* port_name)

INPUT PARAMETERS

       service_name  A service name (string).

       info	     Options to the name service functions (handle). No options currently supported.

OUTPUT PARAMETERS

       port_name     a port name (string).

       IERROR	     Fortran only: Error status (integer).

DESCRIPTION

       This  function retrieves a port_name published under service_name by a previous invocation of MPI_Publish_name. The application must supply
       a port_name buffer large enough to hold the largest possible port name (i.e., MPI_MAX_PORT_NAME bytes).

       The info parameter should be MPI_INFO_NULL, as this routine does not parse any MPI Info arguments.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions  do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except  for
       I/O  function  errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

       See the MPI man page for a full list of MPI error codes.

NAME

       MPI_Unpublish_name - Unpublishes a service name

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Unpublish_name(char *service_name, MPI_Info info,
	    char *port_name)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_UNPUBLISH_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR)
	    CHARACTER*(*)  SERVICE_NAME, PORT_NAME
	    INTEGER	   INFO, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Unpublish_name(const char* service_name, const MPI::Info& info,
	    char* port_name)

INPUT PARAMETERS

       service_name  A service name (string).

       info	     Options to the name service functions (handle). No options currently supported.

       port_name     A port name (string).

OUTPUT PARAMETER

       IERROR	     Fortran only: Error status (integer).

DESCRIPTION

       This  routine  removes the pair (service_name, port_name) so that applications may no longer retrieve port_name by calling MPI_Lookup_name.
       It is an error to unpublish a service_name that was not published via MPI_Publish_name. Both the service_name and  port_name  arguments	to
       MPI_Unpublish_name must be identical to the arguments to the previous call to MPI_Publish_name.

       The info parameter should be MPI_INFO_NULL, as this routine does not parse any MPI Info arguments.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       Before  the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
       I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN  may	be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
